Cascadia is defined as the combination of historical Oregon County and the Pacific Northwest bioregion (i.e. the watersheds of rivers that flow into the Pacific Ocean through North America's temperate rainforest zone). This region includes modern day Oregon, Idaho, Washington and British Columbia.
Cascadia is characterized by the Juan De Fuca subduction zone which is capable of generating magnitude-9 earthquakes, tsunamis, and volcanic eruptions. In addition to climate change and sea-level rise, these processes are hazardous to the populations of Vancouver, BC; Seattle, WA; Portland, OR and surrounding rural areas.
Because effective mitigation of natural hazards stems directly from scientific understanding of the processes that drive them, our purview is both in core science and in designing mitigation in terms of their societal, economic and sociological impact to advance and support interdisciplinary research and education about Cascadia hazards in order to improve public safety in the Pacific Northwest
